The singer/actress told her Twitter followers of her intentions to chop off her mid-length locks, and on Sunday she uploaded a picture of a hairdresser holding scissors to her bun and declared: "it's happening."

Responding to fans' criticisms over the proposed new style, the former Hannah Montana star wrote, "If you don't have something nice to say don't say anything at all. My hair is attached to my head no one else's and it's going bye bye."

Returning to the site a few hours later, Cyrus proved she had gone through with the drastic cut by uploading several shots of her new look, a platinum blonde pixie style, cropped close to her head on one side.
